Patented Dec. i7, less? UNITED STATES PATENT OFFICE Alfred L. Rosenmund, Rockaway, and George P. Igleheart, Boonton, N. J., assignors to stapling Machines (30., a corporation of Delaware Application July 13, 1934, Serial No. 734,906

27 Claims.

This invention relates to machines for equipping wired box parts with interengageable fasteners and particularly to machines for manipulat'ng a wire secured to a box part to provide the wire end with a bight and to perpetuate that bight by driving the end of the wire into the box part.

It is an object of the invention to provide certain improvements in the machine shown and described in U. S. patent to A. L. Rosenmund No. 1,933,031 of October 31, 1933.

It is a further object to provide a machine of the type shown in said Rosenmund patent with improved means for locating and driving the end of the wire into the box parts.

One illustrative embodiment of the invention is shown in the accompanying drawings in which:-

Figs. 17 to 22 inclusive are diagrammatic perspective views illustrating the positions of the locator-driver unit during different phases of its cycle of operation.

One illustrative product of the machine of this application is shown in Figs. 9 and 10. Fig. 9 discloses a wire-bound box blank consisting of a plurality of sections of cleats A and side sheets B connected together by binding wires C stapled to the several sections. Such wirebound box blanks are made on a box blank machine which staples the wires to the several sections. As successive box blanks emerge from. the box blank machine they are connected by the binding wires C, appropriate spaces being left between successive box blanks to permit severing the wires and manipulating the severed ends to provide bights D (see Fig. 9) which bights may be interengaged to close the box, as shown in Fig.

As the wire-connected box blanks emerge from the box blank machine they are fed into the machine of this application and positioned on a vertically movable support or table T, as shown diagrammatically in Fig. 3. As there shown, in the dotted lines, the wire to be operated upon is located directly above the cutters I, prongforming blocks 2, and bight-forming spindles 3, and below cutter-actuator 4 carrying prongforming elements 5, and also below locator-driver units 6 hereinafter described in detail.

In Fig. 3 the parts are at rest preparatory to the start of the machine. The machine is operated through a one-cycle clutch as explained in said patent to Rosenmund No. 1,933,031, and during one cycle of operation the several wiremanipulating elements go through the successive operations shown diagrammatically in Figs. 3 to 7. I

As shown in Fig. 3 in the full lines, the tabl support first lowers the wire C between cutter members I and into contact with prong-forming blocks 2. In Fig. 4, the cutter actuator 4 carrying prong-forming elements 5 descends operating the cutters l to sever the wire C and bend the severed ends over prong-forming blocks 2 to form prongs P on the ends of the wire. After descent of the cutter-actuator the spindles 3 rise and engage the wire ends. When the cutter-actuator rises, the spindles 3 are partially rotated to swing the prongs over onto the box parts, as shown in Fig. 5. The drivers thereupon descend and drive the prongs into the box parts to perpetuate the bights (see Fig. 6)

The several wire-manipulating elements and the mechanisms for operating the same are disclosed and described in detail in said patent to Rosenmund No. 1,933,031, reference to which is hereby made for a detailed description.

The present invention is directed to an improvement in the driver units which drive the prongs into the box parts to perpetuate the bights, and particularly to the mechanism for locating the prong in correct position beneath the driver and for maintaining it in such position during the driving operation.

In the machine of said Rosenmund Patent No. 1,933,031 the mechanism for locating the prong for a driving operation consists of a pair of arms fixed in spaced' relationship to receive between them the prong to be driven, which arms are mounted independently of the driver unit and adapted to be rocked into locating position beneath the driver just prior to the descent of the driver. Such a locator mechanism while gener ally satisfactory under normal conditions occasionally fails to properly engage and position the prong between the two fixed arms of the 10- cator device. Moreover, the locator mechanism of the said Rosenmund patent being mounted and operated independently of the driver unit requires a separate and somewhat complicated operating mechanism to operate the locator in correlation with the operation of the driver unit.

The present invention is intended to eliminate the objections referred to above and to provide a locator mechanism which is mounted on and becomes a part of the driver unit and which consists of relatively movable locator arms adapted to engage and position the prongs regardless of wide variations in the position of the prong as a result of the bight-forming operation.

Referring to Fig. 11, the locator and driver unit is carried on a cross bar I which is reciprocated vertically in the manner described in said Rosenmund patent. The locating and driving elements are supported by a body casting 8 secured to the cross bar 1 by a front plate 9 and bolts l0.

Referring now to Fig. 13, there is secured to casting l2 which carries a driver l3 secured to the casting l2 by bolts l4. At either side of the casting l2 are located side plates l5 which are yieldingly held in contact with the casting l2 by bolts H and I6 and spring l'l.

Mounted to slide vertically in the casting I2 is the locator consisting of a body portion l8, a fixed locator arm NA and a relatively movable locator arm I8B. Movable'locator arm |8B is pivotally mounted on the body portion l8 by a pin l9. Movable locator arm I813 is normally held in its open position at substantially right angles to the fixed locator arm ISA, as shown in Fig. 13, by the I action of a spring 20, one end of which is fastened in the body portion l8 and the other end of which is fastened in the movable locator arm llB.

Secured to the upper end of the body portion I8 is a rod 2| which extends upwardly through casting i2 and into body casting 8, said castings being suitably bored to receive the rod 2|.

Referring to Fig. 16, the upper end of the rod 2| is provided witha lug 22 adapted when the rod 2! is in raised position to be engaged and held in raised position by a latch 23 pivotally mounted at the upper end of body casting 8. Latch 23 is 25 yieldingly held in engagement with lug 22 through the action of a spring 2!.

Body casting 8 and casting l2 are counterbored to receive a compression spring 25 which surrounds the rod 2| and the lower end of which 30 bears against the body portion I 8 of the locator and the upper end of which bears against shoulders 26 of the counter-bore. The tendency of the spring 25 is to force the body portion l8 with its arms I8A and NB downward when the latch 35 23 is released from engagement with the lug 22 on the rod 2|, thus forcing the locator arms "A and I8B out of the casting l2 and permitting movable locator arm I8B to swing into the open position shown in Fig. 13.

40 Latch 23 is released from engagement with lug 22 on the upstroke of the driver-locator unit by a fixed rod or bar 21 carried by the side frames of the machine. When the upper end of the latch 23 strikes the fixed bar 21 the spring 24 is de- 45 pressed and the latch 23 is swung out of engagement with the lug 22 to the position shown in dotted lines in Fig. 16. When the latch 23 is released from engagement with the lug 22, compression spring 25 immediately moves the rod 2| 50 carrying the body portion l8 and its arms ISA and IBB downward to the position shown in Fig. 13. This downward movement of the locator permits movable locator arm HIE to move into the open position shown in Fig. 13.

Driver l3 which is secured to casting l2 extends into the space between arms ISA and I 8B. Said space extends up into the body portion I 3 of the locator a sumcient distance so that the locator arms may be forced out of the casting 0 Fig. 13 the prong P which is to be located and driven has been swung over onto the box part X by the bight-forming sprindle 3.

The locator-driver unit continues to descend until fixed locator arm I8A contacts with the box the lower end of body casting 8 by rivets II a part X, whereupon downward movement of the 15 arm "A is arrested. Further downward movement of castings 8 and 12 lane movable locator armi8B from the open position shown in Fig. 13 to the closed position shown in Fig. 14. During this movement locator arm I83 engages the prong P and moves it over against fixed locator arm I8A directly beneath the driver i8 which continues to descend between locator arms I8A and I813, driving the prong into the box part, as shown in'Fig. 15.

During the driving movement the compression spring 28 has been compressed, as shown in Fig. 16; and the lug 22 on the top of rod 2i has been forced upwardly a suflicient distance within body casting 8 to permit the latch 28 to engage lug 22 and hold the rod 2| in its raised position. Thus, on the upstroke oi the vertically reciprocating cross bar I the locator-driver unit is raised to stop position with locator arms I8A and i813 held within the casting i2.

The cycle of operation of the locator-driver unit is best shown in Figs. 1'7 to 22 inclusive. In Fig-I 17 the machine is at rest and a box part X carrying its wire C has been placed on the supporting table in position to be operated upon by the machine'oi' the application.

In Fig. 18 the machine has been started and the cross bar I has risen, causing the fixed cross bar 21 to depress the upper end of the latch 23 and release the latch from engagement with the lug 22, thereby permitting the compression spring 25 to force locator arms I8A and I8B out of casting l2 and permitting movable locator arm MB to take the open position shown in Fig. 18.

In Fig. 19 the cross bar I has moved the locatordrlver unit downwardly to the point where the fixed locator arm I8A has contacted with the box part X. As the locator arm ISA contacts with the box part X the bight-forming spindle swings the prong P over the box part and toward fixed locator arm I8A, as shown.

In Fig. 20 continued downward movement of the cross bar 1 causes casting H to force movable locator arm I8B toward fixed locator arm I8A until said arms are in the position shown in Fig. 20. Movement of the locator arm IBB from the position shown in Fig. 19 to the position shown in Fig. 20 moves the prong P over against fixed locator arm I8A and holds the prong between the two locator arms directly beneath the be driven into the box part X by the driver i3.

In Fig. 21, the cross bar 1 has reached the lowermost point otits travel and has caused the driver to drive the prong through the box part X and to clinch the point of the prong on a clincher block or anvil 28. During this final drive movement the locator arms MA and I8B are forced up into the casting l2 and the rod 2i carrying the locator N has been forced up into casting 8 far enough to permit the latch 23 to engage the lug 22 and hold the locator arms within cast- -ing l2 until released on the next upward movement of the bar I.

The one cycle clutch disconnects when the locator-driver unit is in the position shown in Fig. 22, permitting the finished box part to be removed from the machine and another box part inserted for the next operation.

While only one locator-driver unit is illustrated and described herein, it will be understood that two such units are usually provided for each wire to be operated upon so that bights may be formed and perpetuated simultaneously on two wire-connected box parts. i

The locator-driver unit of "this invention is durable in construction, reliable in operation, and consists of but few operating parts.

It will be understood that the invention is not to be limited to the preferred embodiment shown 5 for purposes 01' illustration.

It will also be understood that all of the inventive features need not be used coniointly but may be used in various combinations as defined in the sub-joined claims.
